Still, most people who develop breast cancer did not inherit a genetic mutation linked to breast cancer and have no family history of the disease. If one family member has a genetic mutation linked to breast cancer, it does not mean that all family members will have it. Breast cancers associated with a BRCA1 or BRCA2 mutation tend to develop in younger women and occur more often in both breasts than cancers in women without these genetic mutations.
This is about 80 times greater than average. Men with a BRCA1 mutation have a slightly higher risk of prostate cancer. Men with a BRCA2 mutation are 7 times more likely than men without the mutation to develop prostate cancer. Mutations in other genes are also associated with breast cancer. Still, because these genetic mutations are even rarer, they haven't been studied as much as the BRCA mutations.
